The invention relates to certain improvements in oil check rings for self-lubricating journal boxes, such as usually employed on;

railway cars and the like, and has for its obs ject to provide a check ring with an abutment to take up thethrust of the journal bearing,

accom-ip The invention is illustrated in the panyin drawing, in which':

The

with the fillets, but usually engage the same 7 along a relatively narrow arcua-te surface,* with the result that heavy vertical stresses,

are imposed upon theends of the bearings causing the latter to crystallize and eventually crumble and disintegrate. An object of the present invention is to obviate this ,defect and to provide a lateral thrust receiving abutment for the journal bearing,which will engage substantiall the entiresuperficial'area of the end of the bearing and constitute what is, in effect, an end thrust bearing for the axle and relieve the journal bearing of the vertical stresses applied theretoby the fengagement of the fillet under the oldpractice, a Referring to the drawing, 1 indicates the shank or body of the axle, which is provided with the usual journal section 2 connected to the body by a fillet 3,-the primary object of which is to prevent weakening the axlelby a right-angleshoulder and the secondarypurpose of which is to serve as; an end'thrust bearing for the axle as the'latter moves'ax-' ially with respect to its bearing. lnztheexemplary form of the axle shown, there is pro-- vided a second shoulder {l spaced a short distance inwardly of the filleted shoulder 3.

so that no vertical or radial stresses will be;

will be understood that the check ring is fixed to: the axle and rotates therewith and that the plain face 11 of thehubin engagement with the end of the bearing providesa relatively large area of surface contact which results in alow unit'pressurebetwee'n these parts, thereby greatly reducing the and including'a portion of less diameterthan.
